About This Product
This alternator rotor kit from Standard Motor Products is designed to maintain the charging system's integrity on Big Twin Harley-Davidson models. Engineered to replace OEM 29957-81A, this rotor is compatible with both stock configurations and 32 Amp charging upgrades. The kit provides a reliable magnetic field for the stator, ensuring consistent power delivery to the motorcycle's electrical system. As a critical component of the primary drive assembly, this rotor is built to withstand the heat and vibration inherent in air-cooled V-twin engines. It is an essential replacement part for riders performing maintenance or upgrading their charging capacity for modern electrical accessories.
